New Car Engine Sends Shock Waves Through Auto Industry

Analysis by Nic Halverson
Wed Apr 6, 2011 10:10 AM ET

Despite shifting into higher gear within the consumer's green conscience, hybrid vehicles are still tethered to the gas pump via a fuel-thirsty 100-year-old invention: the internal combustion engine.

However, researchers at Michigan State University have built a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids. Their so-called Wave Disk Generator could greatly improve the efficiency of gas-electric hybrid automobiles and potentially decrease auto emissions up to 90 percent when compared with conventional combustion engines.

The engine has a rotor that's equipped with wave-like channels that trap and mix oxygen and fuel as the rotor spins. These central inlets are blocked off, building pressure within the chamber, causing a shock wave that ignites the compressed air and fuel to transmit energy.

This article is dated 2011

and claims a bigger version of this engine by the end of that year. It's been 3 years now so I wonder what happened to all of this?

Big oil don't likey.

Isn't this one of those things that chevron comes in and buys and puts on the shelf.
I want to be excited but I know better. Like those carburetors from the seventies that get like 300 mpg.
Never saw Em. On the shelf at Exxon.



Looks like some one got an offer too good to refuse....

World's first hybrid?

Irrelevant. Troll!

Why do "news" which are totally unrelated to Ron Paul and the nomination process, appear here?

I looked at your profile...

...Super negative. And you call Bob a troll? He finds a lot of good info, you should apologize to him. Did you ever stop and think how this little motor would put the hurt on those Zillionaires who are trying to control you? Think, man, Think! That's why you are here.

Duh!!! Science &

Tech. Many of us are very interested in offgrid, science, farming, sustainable existance. What are you going to do when the SHTF! LoL! Many of us that have been here for quite some time are prepared. Are You?

If RP is not President there will not be a 2016 election. Hell, I'm not even sure if he is elected if we got it done in time. This is your last chance to LEARN SOMETHING of value. Visit the OFF GRID section and gain the education you never thought you would need. Farming, Science, Medicine. It is all here on the DP.

Now once you have done that, come back to the OP and appologize for your ignorance.

Because you haven't been here long enough...

Because you haven't been here long enough to realise we are a diverse group that is always looking for cures to survive when the SHTF. This does not HARM Ron in any way.

If I disappear from a discussion please forgive me. My 24-7 business requires me to split mid-sentence to serve them. I am not ducking out, I will be back later to catch up.

This is in the Science & Tech section

Nothing wrong with posting it. If you don't like it, don't read it. I find it interesting.

Actually this is cool

It uses some of the dynamic principles of a jet turbine,There have been water pumps designed like this for years,they adapted the same principle in reverse.This might work out well folks depending on testing of the efficiency. It relies on torque, a strong torque output requires no transmission. Just like the Stanley steamer,It had so much torque it needed no transmission.

a) I'm so not a mechanic.. how does it work w/o a tranny? Why don't you need gears?

b) If this was a University project then it was, at least in part, publicly funded... they should open source the device so no one can patent it and anyone can offer conversions out of their shop.

c) if this thing works as advertised it represents the evolution of technology that the world has been waiting for.. we are still using industrial revolution technology to get around.

RE: a) is it because it hooks up to a generator and essential becomes an electric car?

Why is it that people who claim to be for free markets

here, actually do not believe in them. If a new invention works, the companies everybody here claims puts them down would be clamoring to be FIRST to get them to market, because that is where the money is. That and government funded projects, which is the only way to keep most of these inventions alive.

Several "inventions" that are the best thing in the world are announced every year like this, but, most of the time these things work only in the lab and under the best of circumstances. They then also use false or misleading stats, like only 15% of the fuel energy goes into propulsion (maybe at a worst case operating point) or that it can save 1000 pounds (from a drivetrain that weighs less than 1000 pounds to begin with, etc. ) A sub 50 hp engine is not going to weigh much, or go very fast with much of a car.

Interestingly, this seems to share a few concepts somewhat in common with old diesel and gasoline rotary engines (think Mazda RX7)

But to your questions
a - if it had tremendous torque response capacity, it would not need a transmission, but that usually means extremely strong (read heavy) and expensive. Besides, the prototype they are hoping to build is 25 kW - not enough for any car in the US to haul anything. It could be electric, an application for which this engine seems ideal, but the article does not imply that is an essential requirement.
b - ideas are patentable to give inventors and their supporters royalties. Universities have various deals to capitalize on their patents
c - modern engines are extremely high tech. Yes, thermal efficiency is not high, but that is due to physical laws. As a function of achievable efficiency in the real world, they are extremely efficient.

Why are you putting words in

Why are you putting words in my mouth I didn't issue? I believe in the free market.. (do you really think we have a free market in this country?) Many "inventions" take time to develop and get right. The light bulb took a long time, as did rocket science etc. Just because there isn't a clamor to get it sold right away doesn't mean there isn't a good germ of an idea. If they are fudging numbers then cut the funding... do you have proof they are doing that?

A) Thanks

B) I understand how patents work. If they want to capitalize on their invention then have at it. I wasn't saying that the idea shouldn't under any circumstance be capitalized upon. However, if this guy really wants to revolutionize transportation like he seems to indicate, why not open source it and let 1,000's play with it in a grassroots movement? Or should they keep sucking down public money to get it right? Why not an act of charity? I merely offered a suggestion. You indicated I'm anti-free market yet I offered a solution that didn't involve lots and lots of public funds and somehow I'm not the capitalist in the room? Do you object to the public funding? Is that free market?

c) It's still old tech (it's only high tech relative to what it used to be), and it still requires the use of a lot of oil products. It's becoming rarer, more sought after and expensive. If something has the potential to break this cycle then excuse me for getting a little bit optimistic. Fuel prices are having a huge negative impact on many, including myself. Not to mention the fact that we are literaly engaged in resource wars over oil and it's only going to get worse.

I think I can answer the first question

The article talks about using it in gas/electric hybrids. You would use the engine as needed to charge the batteries. Propulsion would be provided exclusively by electric motors.

I remember reading about this

I remember reading about this last year soon after it came out. I wouldnt count it out yet as any new engine design today still needs to undergo testing etc. If we dont start seeing something come of this in the next couple years, I would then start wondering.

To climb the mountain, you must believe you can.
